are used with each other, in combination with other functionality, or when used over time, specifically with the risk of correlation of data and user identification through fingerprinting. Web application developers using these JavaScript APIs should consider how this information might be correlated with other information and the privacy risks that might be created. The potential risks of collection of such data over a longer period of time should also be considered.

Variations in
sensor readings
as well as event firing rates offer the possibility of fingerprinting to identify users. User agents may reduce the risk by limiting event rates available to web application developers.

Minimizing the accuracy of a sensor’s readout generally decreases the risk of fingerprinting. User agents should not provide unnecessarily verbose readouts of sensors data. Each
sensor type
should be assessed individually.

If the same JavaScript code using the API can be used simultaneously in different window contexts on the same device it may be possible for that code to correlate the user across those two contexts, creating unanticipated tracking mechanisms.

User agents should consider providing the user an indication of when the
sensor
is used and allowing the user to disable it. Additionally, user agents may consider allowing the user to verify past and current sensor use patterns.

Web application developers that use
sensors
should perform a privacy impact assessment of their application taking all aspects of their application into consideration.

Ability to detect a full working set of sensors on a device can form an identifier and could be used for fingerprinting.

A combination of selected sensors can potentially be used to form an out of band communication channel between devices.

Sensors can potentially be used in cross-device linking and tracking of a user.

Under this type of threat, the attacks use
sensor readings
to locate the device without using GPS or any other location sensors. For example, accelerometer data can be used to infer the location of smartphones by using statistical models to obtain estimated trajectory, then map matching algorithms can be used to obtain predicted location points (within a 200-m radius)

Many user inputs can be inferred from
sensor readings
, this includes a wide range of attacks on user PINs, passwords, and lock patterns (and even touch actions such as click, scroll, and zoom) using motion sensors. These attacks normally train a machine learning algorithm to discover such information about the users. See

Argument

President Donald Trump’s recent decision to withdraw the United States from the Iran nuclear deal and his offer to help Saudi Arabia build nuclear reactors raise the question of just how wild a nuclearized Middle East might get. The dangers of a regional arms race are real. If Iran resumes its nuclear weapons program, the Saudis will certainly pursue their own — and Algeria, Egypt, and Turkey might well follow.

Fortunately, the worst is hardly inevitable. But avoiding it will require deference to energy economics (which, in the Middle East, favor nonnuclear over nuclear forms of energy) and promoting rules against enriching uranium and reprocessing spent reactor fuel (the keys to nuclear weapons development).

Then, there is the unspoken option of culling plutonium from spent fuel generated from its power reactor at Bushehr. Assuming Iran currently lacks a small, crude chemical separation plant (which could be hidden within a moderate sized warehouse), Tehran could build one from scratch in as little as six months. (The design for such a plant was
made public
40 years ago.) Such a plant could process one bomb’s worth of plutonium in about a week and a bomb’s worth per day after that. Given Tehran’s past work on weapons design, it’s reasonable to assume that Iran would have a working implosion device on the ready and could prepare plutonium or highly enriched uranium to place into the device’s core relatively quickly.
